Abstract: PROBLEM TO BE SOLVED: To determine variation in the color of a molten plastic quickly and accurately by introducing a light through a light emitting duct and a sensor head to a molten molding material and transmitting the light reflected therefrom to a spectrometer through a light receiving duct. SOLUTION: Uncolored plastic granules 1 and granules 2 containing a large quantity of coloring agent are fed an extruder 4 having two shafts turning simultaneously at same speed while meshing tightly and heated up to a temperature higher than the melting point while being mixed uniformly. An extrusion molding is delivered to a catcher 5. At the end of the extruder 4 mixed with the free ends of a light emitting duct 7 and a light receiving duct 9, a sensor head 6 projects into the extruder 4 through screw engagement. The light emitting duct 7 is coupled with a light source 8 and the light receiving duct 9 is coupled with a spectrometer 10. Pulse from the spectrometer 10 is delivered to an analyzer 11.

Abstract: The invention relates to a continuous method for producing dyed thermoplastic moulding materials in an extruder, as follows: I) in a first area, A) 10 to 99.999 wt. % of a thermoplastic polymer is metered into an extruder. II) In a subsequent area, B) 0.001 to 60 wt. % of a dye is added at a temperature below the particular glass transition temperature of the thermoplastic A). In the subsequent areas, the thermoplastic/dye mixture is heated, the polymer melt is homogenised and the resulting mixture is extruded.

Abstract: A process for the continuous colour measurement of plastic articles by means of a device (I) is new. Light is conducted via a transmitter optical fibre (II) and a sensor head (III) into the plastic melt and the reflected light is guided via a receiver optical fibre (IV) to a spectrometer or multi-range photometer (II) and (IV) are arranged such that they are the same distance apart from each other. Also claimed is (I).
